Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-{3-[(2,4-dichlorophenyl)methoxy]phenyl}-1-(thiophene-2-carbonyl)-1H-pyrazole.
3-{3-[(2,4-dichlorophenyl)methoxy]phenyl}-1-(thiophene-2-carbonyl)-1H-pyrazole (CAS 477712-63-3) is a high-purity analytical reference standard with the molecular formula C21H14Cl2N2O2S and a molecular weight of 429.32 g/mol.
3-{3-[(2,4-dichlorophenyl)methoxy]phenyl}-1-(thiophene-2-carbonyl)-1H-pyrazole (C21H14Cl2N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
